What that means for ducts
New-build ductwork
Roughly 35% of Lakeway's homes were built since 2010. New does not mean clean: the commonest thing we pull out of a five-year-old system is the construction phase itself — drywall fines, sawdust, insulation fiber — plus builder-grade flex that was kinked or crushed on the day and has been throttling that run ever since. Photographs matter more here, not less.
That is a reading of the city’s stock, not a diagnosis of your home. Which of it applies to you is exactly what the camera settles — and why we would rather run one than quote from a postcode.
02Working in Lakeway
The part that changes from street to street.
Lakeway houses are large and they are cut into a hillside, and both facts show up in the mechanical layout rather than in the age of the duct. Most homes here are recent enough that nothing has accumulated from decades of use. What they have instead is two or three separate systems, split by floor or by wing and often tied to zone dampers and a control board, and that changes what an honest quote even looks like. A single price to clean a house means very little on this side of the lake. The number that matters is per system, and in many of these homes only one of them is doing real work. The upper zone runs hard all summer while a lower level built into the slope stays cool, so its system barely cycles, never dehumidifies, and grows things on a coil that is wet more often than it is used. Heat is electric in most of the city, so we are looking at coils and drain pans instead of burners and flues.

03Plenum & Return-Box Cleaning — in this stock
Cleaning a system that is still carrying its own build.
A post-2010 system is usually not dirty in the way people picture. What comes out is the construction phase — drywall fines, sawdust, insulation fiber — that was pulled into open ducts before the house was ever occupied, plus whatever a kinked flex run has been collecting behind the crimp. That is a different cleaning: shorter, more targeted, and far more dependent on the before-and-after photographs, because the difference is not something you can smell.
What if the plenum liner is in bad shape?
We stop and show you rather than bill for a cleaning that can't help. Degraded or moldy duct-board liner can't be restored by cleaning — EPA guidance is clear that porous materials in that condition need replacement, which is HVAC-contractor work.
Can you clean just the plenums without doing the whole system?
Yes — that's precisely what this service is. The plenums are the highest-traffic surfaces in the system, so cleaning them alone delivers outsized value on older systems, from $199.

We stop and show you rather than bill for a cleaning that can't help. Degraded or moldy duct-board liner can't be restored by cleaning — EPA guidance is clear that porous materials in that condition need replacement, which is HVAC-contractor work. Our photos give you exactly what that conversation needs.
Can you clean just the plenums without doing the whole system?
Yes — that's precisely what this service is. The plenums are the highest-traffic surfaces in the system, so cleaning them alone delivers outsized value on older systems, from $199. If the camera later shows the runs need work too, that's a separate, honest conversation with evidence attached.
Why do you quote per system instead of per house?
Because a house here can hold three of them and their condition is rarely the same. Quoting by the address either overcharges you for systems that are already clean or quietly leaves one out. We scope each unit, tell you which ones need work, and price only those. Two clean systems and one that needs attention is a common outcome in this city.
The lower level smells musty and it is the coolest part of the house.
That combination is common on these hillside plans and it is a runtime problem rather than a dirt problem. A system serving a level built into the slope satisfies the thermostat in minutes and shuts off, so it never runs long enough to remove moisture. Cleaning the duct will not change the humidity. Dehumidification, or a change in how that zone is controlled, will.
We have zone dampers. Do they matter for this?
Enough that we check them before anything else. A damper stuck part closed, or a bypass duct dumping supply straight back into the return, reads from inside the house exactly like a blocked branch. It is worth knowing that a control board is the cause before paying someone to brush a duct that was never obstructed in the first place.
